Application filed Jru1y`30, v1923. Serial 110.6545590.

Be it known that I, SiM MA'NNING, a citiy zen of the' United States,L and residentof the city of St; Louis and State of Missouri,

haveinvented certain new .and useful Ini-l provements in .Lubricating Apparatus, of which the following isa specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part thereof.

My invention relatessto improvements in.

lubricating apparatus and has for its primary objectan apparatus designed'to force Y heavy lubricant under pressure to the surr faces to be lubricated.

A further object is 'to construct a lubricating apparatus whereby grease cupscan be readily lled eitherwit-h a solid or semi'- solid lubricant.y ,Y 1

Astill further object is to construct a lubricating apparatus in which heavy oils lor greasescan be placed underY pressure and delivered to lubricant receptacles quickly :and withoutthe person operating thedevice becoming' soiled. A Heretofore, filling grease cups and similar lubricant reservoirs `either withsolid or semi-solid greases; it has been necessaryto use a spatula'to force the lubricant intova cup.; This operation was naturally very greasy and necessitated, as a general rule.`the use of overalls orzotherV special clothing. By the use of my apparatus the lubricant is placed under pressure and forced in'anddoes notvnecessitate any j change of clothes for lubricating a machine.A n

mits the passage of thepin 30. The pin 30 This makes my device especially applicable to motor veliiclesfbecause lformerly 1t was necessary for the person doing the greasing `to crawl underneath the car with a can of grease and work the saine into the proper;

Fig. 3'is a-.bottoin plan view of the gearsupporting frame made use of;

Fig. 4 is a sectional .view taken on the line 4-4 of Fig.` 3 showing the same on a reduced scale;

Figo is a vertical section of vthe Valve employed;` Y f In the construction of my device I employ al lubricator which consists of acylindrical casing 8. The cylindrical casing is provided with a cove-r 9 Onits upper end. YThe screw threads 10 over which a ring 11 is designed to besecured.V The ring 11 isprovided with an inturned flange 12', which The `Harige contactswith the bottom 13. bottom 13 is provided witha shoulder 14 on which a gasket 15 is placed. The gasket 15 lis lto prevent any leakage of oil. The botv tom 13 is also provided with recesses 16fand 17. In the recess 16 is seated the lend 18 of the screw'19, while in ythe recesses 17 are seated the ends 20` of Screws 21. The purpose of these screws willbeexplained in detail later. Located within the cylindrical lower end of the casing 8 is provided with member; 8 is agearsupportingframe con'- f sisting of a 4circular vmember or sleeve 22. This rSleeve has integrally Vformed ribs 23 8oL l which supportfacentral bearing 211. This bearing/j has a-'tapered opening extending ofthe bevel gear 26 is seated.. Located beneath the bearing 24 is a bevel gear 27 into therethrough in' which the tapered hub`25 opening 29 is formed. This opening perpasses Vthrough the hub 31 of thegear 27 a head 34 which kenters the recess 35 in the gear 26, and when the stud is'thus secured there is impossibility of the gears 26 and 27 from being forced apart- Mesliingwith thefgears 26 and 2 7 isa gear 36 which is mounted on a shaft 37. `The shaft 3T has its end 38 reduced in diameter so asto fit within the opening 39 formed in the bearing 24. The gear 36 is held on the shaft 37 by means of a pin or similar fastening vmeans. .40. The cylindrical member k8V as 'well as the gear `supporting frame'is provided with'a screw threaded fopening in which a screw threaded sleeve@ secured.. This holds-the gear and. also throughthe,bifurcation 32 of vthe J stud 33. which passes through .the 'gear 26. This stud is provided on its upper end with curing the gea-r 36 and the shaft B'r'together. Then the washer 42 is placed in position and finally the handle 113. The handle is secured' by means Yot' the pin' 45' which securesthe ratchet le on to the shaft 37. The pins-50 as'will be noted from Fig. 2, are provided with heads, which contact with the inner the recesses 17 and the screw 19 inthe recess These 'recesses are for theV purpose of.

16. providing a bottoni bearing Afor thev screws so that the piston will not bind due to the f iter the bottoni has been rplaced in position, the ring 11 is tightened.y

screws wobbling.

The flange 12 bears against the bottom, while the gasket 15 together with the flange ist makes a leak tight joint. The flexible conduit has its one end then attached to the casing, the other end of the conduit carries the nozzle.

The ller opening is so located as -to be below the piston 55 when the same is raised' to its fullest extent so that any lubricant'introduced into the cylinder will be below the piston.

In operating my device the piston 55 is lirst raised to its uppermost position. This is done by means of the handle and'ratchet arrangement. The plug ,60 is then removed and lubricant placed in the' cylinder. The operation ofthe ratchet is then reversed and the piston forced downward coming in 'contact with the lubricant and placing the same After this has been done,

under pressure. the device is ready for greasing purposes and in order to till a grease cup, all that is necessary is to remove the cap of the cup and introduce the nozzle intothe cup. Then `by a vdow ward pressure of the nozzle the plate `'i' 9 is brought in contact with the upper edge of the cup. raises the valve and allowslubricant to be forced out through the nozzle 7 7 and into the cup. `When the cup is full, it is only necessary to remove the nozzle from the cup Vand the spring 751- will seat the valve and prevent the escape of lubricant. In this way it not necessaryto come. in Contact with the lubricant at all and it is possible to grease a inotorvehicle in a very Vshorttime. I c f u y lVhen it is desired to iise my device for oiling springs, the spray nozzle or tipis attached and then the plate 79 is gripped with the fingers andpulled upwardly thus permitting lubricant to llow from the nozzle and on to the spring in a flat sheet instead of a round stream.

A continued pressure conduit to be turned so Athat the nozzle can be readily yinserted in an oil cup regardless of itslposition. This turning is also essential in the greasing of springs. It the conduit were not so mounted, the saine would 'have to be twisted, which in a short time would cause it to weaken and leak.

y My device is especially applicable for motor vehicles in filling grease` cups, transmis` 'sion and differential casings either f with hard or semi-hard grease or with heavy oils and can-alsobe used to advantage in greasing springs because a heavy oilrcan be forced Y Vvfrom the nozzle undersuliicient pressure to enable it to enter freely between the leaves 'of thespring and thus accoinplisha very thoroughlubrication.V

My device can be so constructed as to be mounted either on the dash-board of an automobile underneath vthe hood, or it can beV carried yin the tool box. It can also be made large enough to contain oils and grease for sorvicestations. Y y

Vhile I have shown my device as having the pressure mechanism hand operated, still it is obvious that by very slight changes in construction, the same can' be power driven. In fact the power driven device ispreferable for large lubricators. This dilierent driving power mechanism however,`is obvious and therefore is not shown or described in detail. g v l .A

Oneof the 'essential points inA my device is the screws 21 which 'prevent the turning of the piston 55.VV These screws are so threaded and geared as t0 have the same ra tio oi' feed as the screw 19. This lis very es-y sential in tlie'operation ofv my device be- *cause if the screws did not lall feediiat the* same rate, it would be impossible to move the piston either up or down without strip-f )ine threads.Y M ur Jose of Vusinlr'screws '.21 is that there will bey'less leakage of aA thin lubricant under pressure past the screw threads than would be possible'were smooth shafts used, although if found desirable a smooth shaft with a packing gland could be used, .and in this event the gears 17, 19 and 52 are dispensedwith. f

By my construction, it is not necessary to a twisting strain in rotating the gear.

Having' fully described my invention what I claim 51st Y y 1. A lubricator comprising a casing hav` ing a cover and bottom' secured thereto, a

piston located within said casing, a sleeve located in said casing'adjacent the cover, a plurality of gears located within said sleeve and' operatable from Wlthout the oasmg, a
